    Frequently Asked Questions +
    Is a 1 carat heart cut Lab Grown diamond a good size for an engagement ring? +
    Yes. A 1 carat heart cut diamond is a romantic, meaningful size for an engagement ring. It offers clear heart definition, noticeable presence on the hand, and symbolises love in a direct, visual way without feeling too large for everyday wear.
    Does a 1 carat heart cut look smaller than a 1 carat round diamond? +
    Heart cuts can appear slightly smaller face-up than round diamonds of the same carat because some weight sits in the pavilion and lower half. However, the distinctive heart outline draws attention and often feels more eye-catching and emotional than the size alone suggests.
    What makes a well-cut 1 carat heart diamond look beautiful and balanced? +
    A good heart cut has a clearly defined cleft (the “V” at the top), evenly rounded lobes, and a point that sits on the centre line of the stone. Symmetry is critical — both halves of the heart should mirror each other when you visually divide the diamond down the middle.
    Do 1 carat heart cut Lab Grown diamonds sparkle as much as other brilliant cuts? +
    Heart cuts use brilliant-style faceting, so they can be very lively and sparkly, especially around the lobes. They sometimes show a slight “bow-tie” effect in the centre, which is normal, but a well-cut stone will keep this subtle and maintain bright overall brilliance.
    Which color and clarity grades are ideal for a 1 carat heart cut Lab Grown diamond? +
    Because hearts are open brilliant cuts, they hide minor inclusions reasonably well, but the pointed tip and larger facets can reveal obvious flaws. Many buyers prefer D–H color and VVS–VS clarity for a bright, clean look, especially for a solitaire ring or pendant.
    Are 1 carat heart cut Lab Grown diamonds certified by IGI or GIA? +
    Yes. 1 carat heart cut Lab Grown diamonds can be certified by IGI, GIA, and other international gemological laboratories. The certificate details the diamond’s 4Cs, proportions, polish, symmetry, and growth method (CVD or HPHT).
    Is a 1 carat heart cut diamond practical for everyday wear in jewellery? +
    Yes — as long as the pointed tip is well protected. Settings that use a V-prong or bezel at the bottom point help prevent chipping, making a 1 carat heart cut suitable for daily-wear engagement rings, pendants, and even statement earrings.
    Which settings look best with a 1 carat heart cut Lab Grown diamond? +
    Heart cuts look stunning in solitaire rings, halo designs, three-prong or five-prong settings, and drop pendants. Halos can make a 1 carat heart appear larger, while simple solitaires emphasise the shape and symbolism of the heart itself.
    Does a 1 carat heart cut Lab Grown diamond offer good value compared to mined diamonds? +
    Yes. Lab Grown diamonds typically cost less than mined diamonds, especially in popular sizes like 1 carat. This allows you to choose higher color and clarity in a heart cut while staying within your budget or investing more in the setting design.
    Is a 1 carat heart cut Lab Grown diamond suitable only for rings, or also for pendants and earrings? +
    Heart cuts are very versatile. A 1 carat heart diamond is perfect as a centre stone in engagement rings, and also looks beautiful as a solitaire pendant, a centre stone in a lariat necklace, or in romantic drop earrings.
